Book Description
This is a pictorial history of Jack Northrop's dream, the B-2A Spirit, a low-observable, strategic, long-range, heavy bomber with the ability to penetrate sophisticated and dense enemy air-defense shields. It is capable of all-altitude attack missions up to 50,000 feet, with a range of more than 6,000 nautical miles (nm) unrefueled, and over 10,000 nm with one refueling, giving it the ability to fly to any point in the world within hours. Stealth technology has rendered radar systems ineffective by greatly reducing their detection ranges. After ten years of service, the B-2A finally achieved full operational capability in December 2003. An assessment published by the USAF showed that two B-2As armed with precision weaponry could do the job of seventy-five conventional aircraft.

Book Description
Materials with nanoscale structure (i.e. a structure of less than 100 nanometers in size) represent a new and exciting field of research. These materials can be produced in many ways, possess a number of unique properties compared with coarser-scaled structures, and have several possible applications with significant technological importance. Based on a state-of-the-art survey of research findings and commercial prospects, this new book concludes that much work remains to be done in characterizing these structures and their exceptional properties, and presents recommendations for the specific research and development activities needed to fill these gaps in our understanding.

Book Description
This report contains fifteen presentations from a workshop on best practices in managing diversity, hosted by the NAE Committee on Diversity in the Engineering Workforce on October 29-30, 2001. NAE (National Academy of Engineering) president William Wulf, IBM vice-president Nicholas Donofrio, and Ford vice-president James Padilla address the business case for diversity, and representatives of leading engineering employers discuss how to increase the recruitment, retention, and advancement of women and underrepresented minorities in engineering careers. Other speakers focus on mentoring, globalization, affirmative action backlash, and dealing with lawsuits. Corporate engineering and human resources managers attended the workshop and discussed diversity issues faced by corporations that employ engineers. Summaries of the discussions are also included in the report.

Book Description
Designed to protect the privacy of individual student test scores, grades, and other education records, the Family Educational Rights and Privacy Act (FERPA) of 1974 places limits the access of educational researches, and slows research not only in education but also in related fields, such as child welfare and health. Recent trends have converged to greatly increase the supply of data on student performance in public schools. Education policies now emphasize education standards and testing to measure progress toward those standards, as well as rigorous education research. At the same time, private firms and public agencies, including schools, have replaced most paper records with electronic data systems. Although these databases represent a rich source of longitudinal data, researchers' access to the individually identifiable data they contain is limited by the privacy protections of FERPA. To explore possibilities for data access and confidentiality in compliance with FERPA and with the Common Rule for the Protection of Human Subjects, the National Academies and the American Educational Research Association convened the Workshop on Protecting Student Records and Facilitating Education Research in April 2008.

Book Description
In the early 1800s vast fortunes were made in the international fur trade, an enterprise founded upon the effort of a few hundred trappers scattered across the American West. From their ranks came men who still command respect for their daring, skill, and resourcefulness. This volume brings together brief biographies of seventeen leaders of the western fur trade, selected from essays assembled by LeRoy R. Hafen in The Mountain Men and the Fur Trade of the Far West (ten volumes, 1965–72). The subjects and authors are: Etienne Provost (LeRoy R. Hafen); James Ohio Pattie (Ann W. Hafen); Louis Robidoux (David J. Weber); Ewing Young (Harvey L. Carter); David F. Jackson (Carl D. W Hays); Milton G. Sublette (Doyce B. Nunis, Jr.); Lucien Fontenelle (Alan C. Trottman); James Clyman (Charles L. Camp); James P. Beckwourth (Delmot R. Oswald); Edward and Francis Ermatinger (Harriet D. Munnick); John Gantt (Harvey L. Carter); William W. Bent (Samuel P. Arnold); Charles Autobees (Janet Lecompte); Warren Angus Ferris (Lyman C. Pederson, Jr.); Manuel Alvarez (Harold H. Dunham); and Robert Campbell (Harvey L. Carter). Trappers of the Far West is the companion to Mountain Men and Fur Traders of the Far West.

Book Description
The Council, with help from the US Department of Education, held the Millennium Convention in Washington, DC in September 2000. It gathered educators, researchers, and policy makers at the national, state, and local levels to assess success and failure in educating minority and disadvantaged students since the Brown vs, Board of Education decision nearly a half century before, report on research into the causes of the successes and failures, and review strategies and practices that hold promise for continuing improvements.

Book Description
“This profusely illustrated and thoroughly researched book conveys a wealth of information” about the USAF’s B-1 bomber (Aviation History Magazine). When the B-52 Stratofortress entered operational service with the US Air Force in 1955, work was already underway on defining its successor. The B-70 Valkyrie, a Mach 3 jet bomber, was one option. Although two XB-70A prototypes flew, the B-70 never went into production. Out of the subsequent Advanced Manned Strategic Aircraft program came the B-1A bomber, which flew at high speed and low altitude to evade enemy air defenses. But the B-1A was cancelled in favor of fitting the B-52 with cruise missiles. The B-1, known as the BONE, was revived in 1981 as the improved B-1B to boost American military power and serve as a symbol of American strength at the peak of Cold War tensions. The B-1B entered service in 1986 with several deficiencies. The resolution of most of these issues coincided with the end of the Cold War. After the Cold War, the B-1B lost its primary nuclear mission but remained relevant by transforming into a high-speed, long-range, high-payload delivery platform for conventional precision-guided munitions. The first combat use of the B-1B was in 1998 in Iraq. The BONE has proved a highly effective combat aircraft in Afghanistan, Iraq, Libya, Syria, and the former Yugoslavia. This extensively illustrated book traces the BONE’s long development and operational history in detail. “A must-read book . . . a great reference for historians, pilots, engineers, and even policy makers. Both the writing and photos are excellent.” —Air & Space Power History
